The cavity hydraulic ejection system is shown in figure 1.
Design specifications:
1. The common practice of hydraulic ejection is to stick out the ejector plate, and hangs the hydraulic block directly on the ejector plate.
2. For balance, the position of the hydraulic on the left and right should be obliquely symmetrically distributed centered on the ejector plate.
3. Location must be done between the hydric and the template, preferably with a locater block, to ensure that the direction of the hydraulic is parallel to the direction of the ejector plate, as shown in Figure 2.
4. The hydraulic on the left and right must be synchronized, and the two hydraulics must be a group.
